A novel MPEG-2 audio decoder with efficient data arrangement and memory configuration

摘要

The paper describes a novel MPEG-2 audio decoder with a new modified scheme. In the techniques of intelligent data arrangement, the complexity of the multichannel decoding can be largely reduced. In the modified decoding scheme, the bottleneck computation module can be reduced to a quarter of the size of the original. Also, the major memory storage only requires half the size of the standard synthesis subband filterbank.
